Temos o prazer de anunciar a nossa mais recente chamada API : linode.clone(). Esta chamada API permite-lhe clonar facilmente um Linode existente para uma nova instância no datacenter da sua escolha. Irá clonar todos os perfis de configuração e imagens de disco presentes no Linode de origem.
O método tem um limite de cinco clones simultâneos da mesma fonte Linode, a fim de proteger a infraestrutura Linode. Se você tentar executar outro clone enquanto estiver no limite da concorrência, a API retornará com um erro de "validação". Se desejar executar um processo de clonagem em grande escala, o Linode original pode ser clonado cinco vezes, depois, quando esses clones terminarem, os Linodes clonados podem ser clonados cinco vezes ao mesmo tempo, e assim por diante. Isto permite escalar rapidamente a sua infraestrutura de um único Linode para centenas.
Esperamos que você aproveite esta nova chamada API e que ela seja útil para suas futuras implantações na Linode Cloud.
We’ve been looking for something like this for a while
Are there any pre-requisites for this API Call?
Is the Linode need to be shutdown or will be shutdown during the clone process?
How long would it take to clone? Is it the same thing as if its done from the console?
AWESOME! Been waiting for this for so long, at least now we can script our scaling activities!
Can we get one for checking the amount of bandwidth/transfer used for the current month next? (To compare against the existing call for finding the quota.)
> Is the Linode need to be shutdown or will be shutdown during the clone process?
“It is recommended that the source Linode be powered down during the clone.”
The source Linode doesn’t have to be powered down, but it is recommended to ensure that a consistent copy of your data is cloned.
> How long would it take to clone? Is it the same thing as if its done from the console?
1-2 minutes per GB of data within the same datacenter of the source Linode (the Linode you’re cloning from), or 5-10 minutes per GB of data if migrating to a different datacenter.
I assume that you should not .clone() a Linode that has static networking set up, since the static confi will render the new node unreachable… or am I missing something?
You could still clone the Linode, but you’d need to use LISH to log in to the new Linode and adjust the networking configuration to the new IP address(es).
There isn’t currently a way to see how much transfer a particular Linode has used that I can see, but account.info() shows transfer pool amount and usage:
How would you suggest auto scaling in an HA environment where you want to clone and configure network addresses all in one go?
The limitation of 5 clones per source linode seems very arbitrary – you’re just offloading additional work to the side of the script doing the cloning. You might think we’re going to keep track of the clone count on our own, but the truth is we’re just going to iterate over existing linodes until the clone() call returns without an error.
What difference could it possibly make on your end whether we clone a single linode 10 times versus cloning an initial linode 5 times, and then cloning the first clone 5 additional times? There should be no difference in your ability to “protect Linode infrastructure”..?
Xof brought up a good question regarding the static networking setup causing new node unreachable. May I know what is the best solution for that in Linode? Doug’s suggestion to login using LISH and change it manually doesn’t make sense to me, as it defeats the purpose of autoscaling.
